Triangle NGM is reflected across the x-axis, and is dilated by a factor of
\(2 \frac{1}{2} \)
what are the coordinates of vertices N'G'M'
The coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).
From the given graph, N(-4, 6), M(-6, 2) and G(-2, 4).
Scale factor = \(2\frac{1}{2}\)
= 2.5
The reflection of point (x, y) across the x-axis is (x, -y).
Here, N(-4, 6)→(-4, -6)
M(-6, 2)→(-6, -2)
G(-2, 4)→(-2, -4)
Now, with scale factor 2.5, we get
(-4, -6)→2.5(-4, -6)→N'(-10, -15)
(-6, -2)→2.5(-6, -2)→M'(-15, -5)
(-2, -4)→2.5(-2, -4)→G'(-5, -10)
Therefore, the coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

Hey there! Here is your answer:
Varun can make 36 loaves of bread.
Explanation:
The measuring cup holds 27in³ of flour.
Since he has enough flour to fill this measuring cup exactly 120 times.
Therefore, he has 3,240in³ (27in³ * 120) of flour.
Given that 1in³ of flour weighs 0.4 oz,
This implies that there are 1,296 oz (3,240in³ * 0.4 oz) of flour
Since the bread recipe per loaf consumes 36 oz of flour,
Therefore, the number of loaves Varun can make is: 36 (1,296 oz / 36 oz)
I really hope this answer helped you out! Have a lovely day!
Answer:
1000 loafs of bread
Step-by-step explanation:
We know he needs 36 oz. for every loaf of bread. His measuring cup is 27 in.
Divide 36 by 0.4 (1 in is = to 0.4)
You get 90. Multiply 90 by 120 (120 is the amount of times he can fill the cup)
you get 10800
than divide 10800 by the oz for one inch.
You have inches now and can then divide 27000 by 27
Which equals 1000

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500

Josiah kept track of how many songs of each genre were played in an hour from his MP3 player. The counts are displayed in the table below. He has a total of 1,500 songs on his player. Josiah predicted the number of rock songs on his MP3 player to be 300 songs. Which statements about his solution are true? Select three choices. Josiah’s Music Sample 1 Sample 2 R & B 5 R & B 4 Pop 4 Pop 3 Classical 3 Classical 5 Jazz 2 Jazz 4 Rock 6 Rock 4 Josiah’s work: StartFraction 10 over 20 EndFraction = StartFraction x over 1,500 EndFraction. StartFraction 10 times 30 over 20 times 30 EndFraction = StartFraction x over 1,500 EndFraction. 300 = x. He should have found the average of the number of rock songs by averaging 4 and 6 to get 5. He did not multiply the numerator and denominator by the correct number to equal 1,500. His answer will be one-half of what he got because he did not divide 10 by 2 when setting up the proportion. He can only solve the proportion by multiplying the numerator and denominator by a common multiple. He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500
Answer:
Answer is B)
Step-by-step explanation:
Josiah's mistake is (b) He did not multiply the numerator and denominator by the correct number to equal 1,500
The proportion is given as:
Multiply both sides by 1500
Evaluate the expression on the right-hand side
Multiply 10 by 1500 on the left-hand side
Divide 15000 by 20 on the left-hand side
Rewrite the equation as:
From the question, we can see that the products are not well carried out.
Hence, Josiah's mistake is (b)
He got the rock songs part right. He did not multiply the numerator and denominator by the correct number until 1500.
What is Fraction ?What is fraction and example?
A fraction is numerical value that is a part of a whole. It is evaluated by dividing a whole into number of parts
Types of Fractions Proper fraction,Improper fraction,Mixed fraction,Like fractions,Unlike fractions,Equivalent fractions.
The statements that are true about Josiah's solution are:
He correctly found the proportion of rock songs by setting the ratio (number of rock songs in the sample) / (total number of songs in the sample) = (number of rock songs in the MP3 player) / (total number of songs in the sample). sample MP3 player) and solving for x:
Start Fraction 10 over 20 EndFraction = Start Fraction x over 1500 End Fraction.
Initial fraction 10 times 30 over 20 times 30 final fraction = initial fraction x over 1500 final fraction.
300 = x.
He didn't hit the average of the rock songs right because the average of 4 and 6 is 5, not 300.
He did not multiply the numerator and denominator by the correct number to 1500 because he should have multiplied both by 75 instead of 30 to get:
Initial fraction 10 times 75 over 20 times 75 final fraction = initial fraction x over 1500 final fraction. He did not have to divide 10 by 2 when he determined the ratio, because the ratio is already in its simplest form. So the real arguments are:
He got the rock songs part right. He did not multiply the numerator and denominator by the correct number until 1500. He did not have to divide 10 by 2 to determine the ratio.

There were about 316 principals in attendance.
There were about 483 principals in attendance.
There were about 1,878 principals in attendance.
There were about 483 principals in attendance.
The correct option is (3).
What is Arithmetic?The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations.
As per the given data:
The total number of people in the recent conference = 650
The total number of people in one exhibit room = 70
Number of teachers in one exhibit room = 18
Number of principals in one exhibit room = 52
To find out the total number of exhibit rooms:
= Total number of people in the conference / total people in one room
= 650 / 70
= 9.28 = 9 {rounding off to the nearest integer}
Number of principals in one exhibit room = 52
Total number of principals in the conference:
= Number of rooms × Principals in one room
= 9 × 52 = 468 which is equal to 483 {approximate answer}

A: create an equation using x and y to represent the line shown
b: create an equation using x and y that has the same slope as the line shown and passes through the origin
Answer:
A. \(y=\frac{3}{2}x-1\)
B. \(y=\frac{3}{2}x\)
Step-by-step explanation:
For the graph shown, the slope is \(\frac{3}{2}\) and the y-intercept is -1.
PLEASE MARK THIS AS BRAINLIEST!!!!
Answer:
A: y= 1.5x -1
B: y= 1.5x + 0
Step-by-step explanation:
The formula to find slope is y=mx+b, m being the slope and b being the y intercept.
In A, the line shown passes through -1 on the y axis.
The slope is 1.5. An easier way to see that is to grab two points on the line and do this: (y2-y1 over x2-x1) It can be any points you like, as well.
I will use (2, 2) and (-2, -4), as these points are both found on the line, and they are exact.
So, first we will do this: we will take the two ys, y1 and y2. You don't have to do it like that, but sometimes it is easier just to take the higher value first. BUT! You do have to do it y over x, not x over y. Watch:
2- -4 = 6
____ ___
2 - -2 = 4
So your slope is 6/4 OR it is 1.5.
So for b, if they are asking you to create an equation with the same slope but it goes through the origin, then your next equation would be y= 1.5x+0. Since the original is represented by (0, 0), then you will have the y axis and y intercept at 0.
I hope this helps you!

Step-by-step explanation:
To find p^6(-1/2), we need to repeatedly apply the function p(x) to the value -1/2 six times:
p(x) = 1 - 1/x
p(-1/2) = 1 - 1/(-1/2) = 1 - (-2) = 3
p(p(-1/2)) = p(3) = 1 - 1/3 = 2/3
p(p(p(-1/2))) = p(2/3) = 1 - 3/2 = -1/2
p(p(p(p(-1/2)))) = p(-1/2) = 3
p(p(p(p(p(-1/2))))) = p(3) = 1 - 1/3 = 2/3
p(p(p(p(p(p(-1/2)))))) = p(2/3) = 1 - 3/2 = -1/2
Therefore, p^6(-1/2) = -1/2.
